I do not know Linux' current behaviour, especially with recent filesystems. I seem to remember from last century that Linux by default automatically issues a sync every 30s. So every filesystem that is writable and uses a write-back-cache (i.e. that doesn't right writeaway) would have a 0s?30s amnesy window. (V)FAT would be a candidate, but SD cards usually are parameterized at mount to actually write through, i.e. are less efficient but have no problem. I have no clue what journalling file systems do here. S.M. -- Dipl.-Phys.
